SLY-890机制砂形粒分析仪

一、产品介绍：

机制砂形粒分析仪主要适用于粗的、粒状材料的粒度粒形分析领域，如金刚砂、研磨材料、机制沙、河沙等。它的测试过程是将样品放到储料漏斗里，通过电磁振动加料器和布料槽将颗粒分散开，并在布料槽的末端自由下落，高速摄像机在下落过程中拍摄颗粒图像，并通过电脑对这些图像进行分析，从而得到粒度与粒形数据。

1. Product introduction:

The machine-made sand shape analyzer is mainly used in the field of coarse and granular materials, such as emery, abrasive materials, machine-made sand, river sand, etc. Its test process is to put the sample in the storage hopper, disperse the particles through the electromagnetic vibration feeder and the cloth trough, and fall freely at the end of the cloth trough. The high-speed camera captures the image of the particles during the falling process, and the computer monitors the particles. These images are analyzed to obtain particle size and shape data.

二、试验方法：

机制砂形粒分析仪是在颗粒下落状态下拍摄颗粒图像的，这种系统可实现亚毫米和毫米级的颗粒的精确粒度粒形测量，在粗颗粒的粒度粒形分析领域一枝独秀。它通过分散和布料系统实现自动进样，不但简化操作，还减少了人为因素的影响，提高了准确性。高速摄像机实现动态连续拍摄，一次能拍摄数万、十几万甚至几十万个颗粒，对这么大量的颗粒进行分析，充分保证了样品的代表性好，保证结果准确。同时，图像处理软件能自动判断和提取粘连颗粒，这些技术极大地提高了颗粒图像的分析速度、精度和准确性。独特的颗粒分析软件采用边缘识别的快速图像处理技术，每分钟能处理2万个以上的颗粒，实现了一边拍摄一边在屏幕上显示每个颗粒的图像和粒度粒形数据，就是边拍摄边得到分析结果，拍摄结束，报告单也同时出来。

2. Test method:

The machine-made sand particle analyzer captures particle images when the particles are falling. This system can achieve accurate particle size and shape measurement of sub-millimeter and millimeter particles, and is unique in the field of coarse particle size and shape analysis. It realizes automatic sample introduction through the dispersion and cloth system, which not only simplifies the operation, but also reduces the influence of human factors and improves the accuracy. The high-speed camera realizes dynamic continuous shooting, which can shoot tens of thousands, hundreds of thousands or even hundreds of thousands of particles at a time. The analysis of such a large number of particles fully guarantees the representativeness of the samples and the accuracy of the results. At the same time, the image processing software can automatically determine and extract the adhesion particles. These technologies greatly improve the analysis speed, precision and accuracy of the particle image. The unique particle analysis software adopts the fast image processing technology of edge recognition, which can process more than 20,000 particles per minute, and realizes that the image and particle size and shape data of each particle are displayed on the screen while shooting. Analyze the results, the shooting is over, and the report form will come out at the same time.
